v LUBRICANT-CUP...

'15: I 1 '0 all "whom it may concern: B'e it known that I, Gnonen WV.BOWEN, of Auburn, in the county of Cayuga and State of New York,have'invented a certain new and useful Lubricant-Cup, of which the'following is a specification.

. My invention has for its object the production of a. lubricant cupwhich is particularly simple in construction and economical ofmanufacture; and to this end, 1t-

1 consists in the novel features of construction hereinafter set forthand claimed.

-'In describing my invention, reference is had to theaccompanyingdrawing in which like characters designate corresponding parts in allthe views.

Figure l is an elevation of m'y lubricant cup. Fig. 2 is a verticalsectional view thereof. Fig. 3 is a top plan, partly broken away, of thecap of my cup. Figs. 4 and 5 are sometric views, respectively, of thecap and base thereof. Fig. 6 is a vertical sectional view of a modifiedconstruction of the base of my lubricant cup.

This invention consists of a lubricant cup composed of a plurality ofpart s',=-each of which is pressed from asingle piece of sheet metal. Inthe illustrated exemplification,

the lubricant cup comprises two parts i. e.,

a base 1 and a cap 2. The base leonsists of a main body or receptacle 3and a stem 4, the latter having a passage 5. communicating with theinterior of the main body or receptacle 3. Said main body or receptacle3 is preferably substantially funnel-shaped and preferably formed wit athreaded ring at its larger end for receiving the cap 1 and is providedat its top with an upturned flange of substantially uniform thickness,and the stem 4 is usually provided with a threaded end portion 6 andwith-apart 7 having its inclosing-wall formed of substantially uniformthickness 'and with external and inter- 'nal faces of angularcross-section. The part receives a wrench or any suitable tool forscrewing the base into position. The threaded portion 6 and part 7 areof difi'erent diameters and the stem is thickened (Figs. 2

- and 6) at the line of union of said threaded portion and angular partfor strengthening the stem at this point against breaking when the baseis bein turned into or ,out of position. Prefe'rab y, the threads camestem are provided on theexterior of said pbn- Specification of LettersPatent.

tion 6, but as seen in 6, said threads may formed on the interiorthereof.

In the manufacture of the base 1, a piece of flat sheet metal issubmitted to the action the metal at the juncture of the cylindrical endand the conical part substantially hexagonal in cross-section, thehexagonal part and the c lindrical end forming a stem portion.Subsequently, the extremity of the stem is perforated and thecylindrical end thereof is threaded. These shaping operations condense apart of the metal of the cup intermediate of the body portion and theend of the stem and bring the same to at least its normal density, thusstrengthening the stem and fashioning a part thereof, the hexagonalportion, to serve as a Wrenchhold and condensing the metal at thejuncture between said wrench-hold and the threaded end-or portion tostrengthen the same.

'flhe cap 2 is provided with a knurled hand-engaging portion formed bydistorting the metal of said cap, thereby causing said hand-engagingportion to project from the adjacent part of the cap. As best seen inFig. 3, said hand-engaging portion consists of a plurality of peripheralhollow projections'or corrugations 8 spaced equal diserally relativelyto the adjacent parts of the cap, by pressure acting on the interior ofthe cap in a direction substantially radially relatively to the axis ofthe cap. Said cap is secured to the base 1 by intermeshing "threads 9,10 formed respectively on the periphery of the upturned flange at thetop of the base 1 and on the inner-face of. the lower end of the cap 2.

The cap2 is usually formed from a sheetmetal shell, the peripheralprojections '8- being formed by crushin the crown of the shell andholding the ma or portions of the barrel thereof and portionsalternating with said projections, from contracting or spread- 7 ing,thereby forcing outwardly parts of the formed to engage a supportcheaply and wit The construction of my lubricant cup will tion and theend of densed to strengthen said; stem,
